The original South Park (Jesus and Santa Claus) was done in construction paper. It went to being generated in Maya when it became a series. The design udea is to continue to make it look like construction paper. It's produced in a 3D program to look like 2D. As for it being an "ugly" form of art, well, I never much liked Mona Lisa's smile. It looks like the artist couldn't make up his mind. Beauty is in the eye of the beholder.
